Kiattisak’s place is located in a place near the BTS station Bang Chak, Next to the Station On Nut which has 2 big supermarkets that you can shop for almost everything.
I was able to work there at night with the WiFi he provided and the desk in the bedroom and Kiattisak replied msg as soon as possible usually.
There are also some local small restaurans and cafes near Bang Chak which is great for people like me that is not into fancy stuff much but wish to experience how to live like a local there.
It takes about 20 mins to get to Central Areas by BTS so you could still go to the fancy restaurants and big malls if you like.
I would recommend this apartment for travelers who love to live as locals there.
